EulerOS Virtualization 2.5.3 : zlib (EulerOS-SA-2019-1276)

High Nessus Plugin ID 123744

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the zlib packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic.(CVE-2016-9840)

- inffast.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic.(CVE-2016-9841)

- The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.(CVE-2016-9842)

- The crc32_big function in crc32.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving big-endian CRC calculation.(CVE-2016-9843)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected zlib packages.
